代理ROHM升降压<font color=red>LED</font>驱动器BD8381EFV-ME

BD8381EFV-M is a white LED driver with the capability of withstanding high input voltage (50V Max.). A current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against voltage input and also to remove the constraint of the number of LEDs in series connection. The brightness can be controlled by either PWM or DC. The PWM brightness signal generation circuit is built into, and the control without microcomputer is also possible.
